1 Claim. (Cl. 155-131) My invention relates generally to infant seats ofthe type disclosed in Patent 2,324,421, and more particularly torelatively inexpensive disposable devices of this character.

The primary object of my invention is the provision of an infant seat ofthe type immediately above described which may be formed from a blank ofrelatively tough paper stock such as corrugated paper board.

A further object of my invention is the provision of a device of theclass immediately above described which is extremely inexpensive toproduce and which is sul'liciently rugged and durable in construction toendure the stresses and strains of normal use for the relatively briefperiod of time for which it was constructed.

A further object of my invention is the provision of a device of theclass immediately above described which, while inexpensive to produce,may be utilized with all the benefits derivable from a more expensiveand pennanent structure of this type.

A further object of my invention is the provision of a device of theclass above described which is extremely light in weight and henceextremely easy to handle, store and ship.

The above and still further objects of my invention will become apparentfrom the following detailed specification, appended claim and attacheddrawings.

Referring to the drawings wherein like characters indic-ate like partsthroughout the several views:

Fig. l is a View in top plan of a blank of corrugated board or the likescored and folded in accordance with my invention;

Fig. 2 is a view in perspective showing partial formation of my novelstructure from the blank of Fig. l;

Fig. 3 is a perspective view on a somewhat reduced scale showing mynovel structure in com-plete and operative condition;

Fig. 4 is an enlarged fragmentary sectional view taken on the line 4 4of Fig. 3;

Fig. 5 is an enlarged fragment-ary View taken on the line 5-5 of Fig. 2;and

Fig. 6 is a fragmentary view in rear elevation of the structure of Fig.3.

Referring with greater particularity to the drawings, the numeral 1indicates in its entirety a blank stamped from corrugated paper boardstock and folded and scored to provide `a back element 2, side wallmembers 3 secured to opposite side edges of the back element 2 alongfold lines 4, and top and bottom wall members 5 and 6 securedrespectively to the upper and lower edges of the back ele-ment 2 alongfold lines 7 and 8 respectively.

Side wall members 3 are shown as comprising matching inner and outersections 3a, 3b which are connected together along central fold lines 9.As shown, each of the sections 3a, 3b taper from their relatively widelower edges 10 to their relatively narrow upper edges 11, whereby todefine upwardly tapering side walls, as shown in Fig. 3, when the innersections 3a are folded inwardly 2,960,149 Patented Nov. 15, 1960 uponthe outer sections 3b, along fold line 9, and the side wall members 3swung at right angles with respect to the back 2 along the fold lines 4.To maintain the side wall members 3 in this operative position, the freeouter edges 12 of the inner side wall sections 3a are formed to providet-a-bs 13 which are insertable into openings or recesses 14 on oppositesides of the back element 2.

The top wall member 5 likewise comprises matching inner and outer wallsections 5a, 5b respectively which are foldab'le along the line 15. Asshown particularly in Fig. 1, the inner section 5a is formed to providetabs 16 along its free outer edge 17 which are adapted to be receivedwithin apertures or recesses 18 adjacent the upper edge of the backelement 2, as defined by the fold line 7. rllhe adjacent opposite sideedges 19 of the outer sections 3b ofthe side wall members 3 are provided'with flaps 20 receivable between the inner and outer wall sections Sa,5b of the top wall member 5 for the purpose of securely locking the topwall member 5 to the side wall members 3 in their operative positions ofFig. 3 wherein they project at right angles to the plane of the backelement 2. Any suitable adhesive may be utilized for securing theelements 5a, Sb and 20 together.

The relatively deep bottom wall forming member 6 likewise comprisesinner and outer matching wall sections 6a, 6b, the free outer edge 21 ofthe inner wall section 6a having tabs 22 receivable in apertures orrecesses 23 in the back-forming element 2, when lche bottom-formingelement 6 is placed in operative position by bending the same at rightangles to the plane of the back-forming element 2, along fold lline 8.The adjacent opposite side edges 24 of the outer side wall members 3bare likewise rformed with aps 25 which are receiv-able between andrigidly adhered to the inner and outer Wall sections 6a, 6b, to lockthese elements together.

To anchor my novel infant seat in a generally upright position to asuitable vertical support, as shown in Fig. 3, I provide a tie member 26which projects through laterally spaced openings 27 in the back element2. For the purpose of securing an infant within the forwardly openingseat, I provide an adjustable girth strap 28, op-

posite ends of which project through laterally spaced openings 29 in theback element 2 intermediate the up per and lower ends thereof. Theextreme outer ends rearwardly of the back element 2 are knotted orotherwise enlarged to discourage their being pulled through the openings29. The intermediate portion of the girth strap 28 is secured to theupper end of la crotch strap 30, the lower end of which is loopedthrough an opening or aperture 31 in the bottom wall member 6intermediate the sides thereof. As shown the aperture 31 is formed byalignable lapertures 31a, 31b in the inner and outer wall sections 6a,6b and 4by alignable notches 31C in the opposed adjacent edges 32 of theaps 25.

The method of use of my novel disposable infant seat above described isidentical with that described in Patent 2,324,421, and las there shownany desired arrangement of cushions or pads, `disposable or otherwise`may be placed in engagement with the back element 2 and the bottom wallmember 6.

My invention has been thoroughly tested and found to be completelysatisfactory for the accomplishment of the above objects, and while Ihave disclosed a preferred embodiment it should be understood that samemay be capable of modification without departure from the scope andspirit of the app-ended claim.

What I claim is:

A foldable and disposable chairback supported seat structure forinfants, comprising a one-piece foldable blank having a substantiallyrectangular back wall por- 3 tion adapted to be mounted on and restagainst said chairback, sidewall portions substantially eoextensive withand foldably connected to opposite sides of said back wall portion,Yeach said side wall portion being obliquely folded upon itselfsubstantially midway 'between its longitudinal outer edge andV itsfoldable conneeton with said back portion and extending normal theretoto provide a reenforeed seat suspending means, foldable end wallportions extending normal to and beyond one end of each of said sidewand back wall portions with said side end Wall portions disposed insuperimposed relation to said back end portion and providing areenforced seat suspended between said folded side 4V portions, `andmeans interconnecting said folded side and superimposed end wallportions to said back wall portion and said back 'Wall portion to achairback.
